We investigate the unsteady laminar convective magnetohydrodynamic nanofluids flow in a square cavity driven by an exothermic chemical reaction. Because exothermic chemical reactions are intrinsic in nanofluidic flow applications. we consider this exothermic chemical reaction in the analysis. which is governed by Arrhenius kinetics energy. https://www.roneverhart.com/Terry-s-Milk-Orange-Chocolate-with-Popping-Candy-12-Piece-Case/
